I tried to mount an NFS volume on my MacBook at home and it was failing. I hadn’t accesed my NFS in a month since I updated to OpenSuse 11.1 or changed some network parameters.
Checking the logs on the server (/var/log/messages) showed this error:
mount request from unknown host
but the IP address seemed good. I checked the exported filesystems:
$ sudo exportfs /home 192.168.13.*
and everything looked fine. Checked the exports(5) man page:
$ man 5 exports
and realized the “*” is meaningless in that context. Changed /etc/exports to use the /24 address for my network:
/home 192.168.13.0/24(fsid=0,root_squash,sync,no_subtree_check)
and re-exported:
$ sudo exportfs -ra
